中文摘要：
本文利用生态足迹法对兰州市1996—2005年的生态足迹和生态承载力进行了研究。结果表明：兰州市人均生态足迹和生态承载力分别由1996年的1．66hm^2、1．56hm^2增加至2005年的2．15hm^2、1．11hm^2，同期的人均生态赤字也由0．10hm^2上升到1．04hm^2分析兰州近几年人均生态足迹和生态承载力的变化趋势。运用相关分析、主成分分析法，分析影响生态足迹的主要因子。目前兰州市的人均生态足迹，已超出了自然生态系统的生态承载力范围，现有的发展模式县信得深思的．
英文摘要：
Ecological footprint is a new method for quantify measuring the sustainable development. The ecological footprint method was used to analyze the ecological footprint and ecological capacity in Lanzhou City during 1996 to 2005. The results showed that ecological footprint and ecological capacity per capital increased from 1.66hm^2, 1.56hm^2 in 1996 to 2.15hm^2 ,1. 11hm^2 in 2005. Ecological deficit increased from 0.10hm^2 in 1996 to 1.04hm^2 in 2005. Principal component analysis method was applied to analyze the main factors affecting the ecological footprint . At present Lanzhou City ecological footprint per capital has gone beyond ecological capacity. Therefore we should pay more attention on the pattern of development .
